I suspect that shutting the ticketing operation and putting out a 'holding' communication that they may not honour the tickets when they realised yesterday lunchtime that there was a problem may have been best. But, of course, that is with hindsight :wink:

It says it was fixed by lunchtime yesterday, so I think so. More likely they're trying to figure out WTF they are going to do before releasing a communication :shrug:
I would go for cancel them all and start again (if there's time).
